Animal Testing Disadvantages

715 Words3 Pages

Over the years, most of the remarkable medical achievements were dependent on scientific testing involving animals. Since the aim of scientific testing is to understand the interactions and processes between levels of structural organization of the human body, animal tests are frequently employed to study biological activities and certain diseases (Royal Society, 2004). While advocates of animal test believe that the use of animals takes a significant role in pharmaceutical development, opponents maintain that it is an exploitation of animal rights. In this essay, the advantages of using animals for scientific testing will first be examined, and then followed by its disadvantages.

The use of animals in scientific testing brings substantial advantages to medical development towards the treatment of human diseases due to their close resemblance to the physical features of human beings. At present, in vitro tests cannot accurately mimic the complex human organism and the complicated chemical reactions between medicines and bodily functions because they do not take all organ activities and functional activities into account. For instance, a drug has to overcome certain barriers and dynamic conditions in the human body before it is being fully absorbed, in vitro tests, however, cannot simulate equivalent conditions (Garattini & Grignaschi, 2016). Therefore, using selected animal species in scientific tests, which have similar organ structures and functions with that of human,

    There is much controversy with regards to animal testing for medical research and there has been throughout the centuries. We can trace the issue back all the way to the 4th century when we have the first record of animal experimentation, Aristotle dissecting animals for study. In the 1600s, scientists began using animals as a way to explore the human body which led to many advancements in the medical field. Such advancements include Emil von Bering finding a cure for diphtheria toxin for guinea pigs; further research allowed him to produce a diphtheria vaccine for humans (Bright).In spite of these many medical achievements brought on through the use of animal testing, there are still those that argue the practice is not justifiable and should

    Many debilitating diseases and conditions have been cured and prevented using vaccinations that were tested on animals. For example, Emil von Behring performed an experiment on guinea pigs that helped form the vaccine for diphtheria (Soft Schools). The significance of this experiment helped von Behring earn a Nobel Prize in Physiology (Soft Schools). Following von Behring’s findings, Edgar Adrian used frogs to confirm the specific way that the brain sends signals to different parts of the body (Soft Schools). Advancements in the understanding of diabetes, tuberculosis, and polio, along with the formation of anesthetics all were successful with the help of animal testing (Soft Schools).

    Animals have similar anatomy to humans, but it is still vastly different. What works on an animal could have a totally different effect on humans. For example, according to the FDA, Vioxx, a drug used to treat arthritis, was found to be safe when tested in monkeys (and five other animal species) but has been estimated to have caused around 320,000 heart attacks and strokes and 140,000 deaths worldwide. This proves that medical testing on animals isn’t necessarily beneficial considering the physiological differences between man and animal. But that’s not the only case of medical testing gone wrong.

Although some of the animals are similar to human, the DNA are different. As a result, the side effects that made by the medicine on animals and humans may not the same. Moreover, the size of humans are different from the animals, the same dose of drug may harmful some small size animals like rabbits but do not have effects on humans.

    In the article The Flaws and Human Harms of Animal Experimentation by Aysha Akhtar, she sums up the average truth and beliefs of someone who knows that this form of testing should be outlawed due to the unreliability of accurate results. In this article, Aysha reveals the validity and unreliability of testing on animals due to the differences in a growing and developing body compared to a helpless non-human animal with a different body make-up. She clearly discusses the number of animals that are being tested annually, “more than 115 million” (Akhtar, p. 407), with either human diseases or medical products. She goes on to say that obviously, medications and diseases should be further researched and have a prior evidence basis before being in contact with humans, though testing on such helpless animals that are not nearly as close to humans as they assume, give a unlikely truth to the results and do not clearly show the effects of medications or diseases would have on the average human (Akhtar, p.

    The new testing method does not provide the opportunity to study interrelated processes occurring in the central nervous system, endocrine system, and immune system. But, animal testing can provide it all. California Biomedical Research Association states that “chimpanzees share more that 99% of DNA with humans and mice share more than 98% DNA with humans, therefore, animals are susceptible to many of the same health problems as humans.” All mammals, including humans, are quite similar with the same set of organs such as heart, kidneys, and lungs which work more or less the same way. So, if we want to examine a new medicine and its effect on our body, animals are the most appropriate choice because animals and humans are so biologically similar.

Such animal testing dates to the mid-19th century when the experimental medical science appeared.

    Animals may assist in the advancement in medicine by acting as test subjects, but this does not mean that we are given the right to neglect their basic needs. In laboratories, animals live stressful and unnatural lives, being locked in crowded cages and deprived of basic resources in order to ‘save resources’. While this may be cost-efficient to prevent using more resources, it also causes harm to animals when basic needs like space, food, and water are not given where needed. Animals are also put through painful procedures, of which most are rather questionable – including permanent infestation of worms in dogs for future studies. One example of this is the commonly used Lethal Dose 50 Percent test – a test that requires animals to be injected with high amounts of toxin to determine what dose will kill 50 percent of test animals.
